How do you choose the right mattress size?
You may have a vague idea about the size of mattress you need.
But actually deciding while you're hunting for a new mattress can be a little more complicated. 🤯
There is no right mattress size.
Instead, the right mattress size for you depends on a variety of factors, including your height and body weight, the size of your bedroom or studio apartment, and your family setup.
The below questions can guide you:
- Are you short, tall, or of average height?
- Are you light-weight, of average weight, or slightly heavier?
- Do you sleep alone or do you share your bed with a partner?
- Do you have children or pets that share your bed with you?
- Are you a restless sleeper?
- If you have a partner, is your partner a restless sleeper?
- How big is your bedroom?
- How big/wide are your staircases, entryways, and corridors?
These questions may not give you a definitive answer, but they will help put you on the right path. ✅
It's also worth noting that bed-in-a-box brands give you the opportunity to try larger beds that traditionally wouldn't have fit through entryways or corridors.
This is very convenient for people with narrow staircases or those living in loft apartments where a larger bed may fit, but carrying it up would have been an issue otherwise.
You can also consider the following:
- If you're buying a replacement mattress, measure your current bed frame and bedding dimensions, and buy a mattress in the same size.
- If you're buying a bed & mattress for the first time or you want to upgrade your bedroom setup, consider your budget (also include costs of the bed frame and bedding) and the size of your bedroom, and choose from there.
These factors can act as a guideline to help you choose your new bed.
Don't forget to always consider the space around your bed as well - i.e. you'll still need space for bedside tables and ensure that the bed doesn't block any doors, windows, or power outlets.
If you're looking to buy a bed and mattress, it may be worth looking into a bundle deal.
These combine a bed frame with a mattress and fitting sleep accessories. 🛌
These are some of our favourite bundle deals:
How long should your mattress be?
Your mattress should be at least 10 cm (3.9 inches) longer than the tallest person using the bed.
- Standard single and double beds only have a length of 190 cm (6'3").
- Standard king, super king, and emperor beds have a length of 200 cm (6'6").
If you're taller than 180 cm (5'9"), you should ideally opt for a bed with a length of 200 cm. 📏
In the UK, only the king, super king, and emperor mattresses have a length of 200 cm.
European mattresses, in contrast, always have a length of 200 cm, so if you're looking for a longer single or double bed, it'd make sense to opt for a brand like Simba that actually sells both UK and EU mattress sizes.
If you're taller than 190 cm (6'2"), though, it'd be best to invest in an extra-length bed for added comfort.
After all, you don't want your feet sticking out at the end of the bed. 🦶
What size should your bed frame be?
Bed sizes UK & mattress sizes UK often go hand-in-hand.
Bed frames are available in a range of different UK bed sizes to match your chosen mattress.
If you choose a super king size mattress size UK, for example, you also need to purchase a super king size bed frame.
The standard bed sizes UK will include:
- Standard small single bed
- Standard single bed
- Standard small double bed
- Standard double bed
- Standard king bed
- Standard super king bed
Some frames aren't available in smaller sizes, so it's always a good idea to check out bed frames and mattresses at the same time.
Will my bed frame fit?
UK bed sizes may come with the same size descriptions as your mattress (such as small, double, or king size bed size UK).
But this does not mean that the bed dimensions will necessarily be the same as the mattress dimensions. 😱
The dimensions of your frame will depend on the style of frame you choose:
- Divan beds or box springs (without a headboard) will have the same dimensions as your mattress since the mattress simply sits on top of the divan base.
- Wooden bed frames are usually slightly larger than your mattress, with a few extra centimetres on each side.
- Upholstered bed frames vary in size, depending on the shape of the frame and fabric used.
Always get accurate measurements of the space available to make sure your desired bed frame will fit and make sure the bed won't block any required power outlets, doors, etc. 📏
Don't forget to take into account the design of the headboard (thicker or curved headboards, like the one on the Simba Orion Bed, take up more space) and whether or not the bed has a foot end.
Beds like the Simba come flat-packed in boxes, so you just need to worry about the space in your room and not how wide your stairways, corridors, or doorways are.
This is super convenient for tight spaces or loft rooms.
Also, keep in mind how much space you'd need for bedside tables or if you need space on both sides of the bed for partners to climb in.
Those with minimal space should opt for a divan base without a headboard.
